The Benefits of Technology in Education: Sangmum Lee at TEDxYouth@BIS 

Sangmun Lee is from South-Korea, where he spent most of his life. When he was young he didn't notice how dangerous electronic devices and internet technology can be, but he finally encountered the truth. He thinks that this problem should be solved in some way or people are going to become slaves to technology. He thought about what part of technology made itself so toxic to us, and the reasons why we are so hooked on tech.
About TEDx, x = independently organized eventIn the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)
